BEMOVING DEVICE FOlR; THE CLOSURE-CAPS OF MILK-BOTTLES AND OTHER RECEP-TACLES.

Application filed January 26, 1915. Serial No. 4,569.

To all whom it may concern:

Be it known that I, THOMAS H. TAYLOR, a citizen of the United States ofAmerica, residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inRemovin Devices for the Closure- Caps of Milk-Bott es and otherReceptacles, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to a removing device for the closure caps of milkbottles and other receptacles and has for its object to provide means,in a manner as hereinafter set forth, for conveniently removing from themouth ofa bottle or receptacle the 010- sure disk, said disk being whatis generally termed a cap and is constructed of flexible material,preferably paper, and when mounted in position is seated within themouth of a bottle or receptacle against a shoulder formed on the wall ofthe mouth.

Further objects of the invention are to provide a removing device forthe closurers for milk bottles and other receptacles which is simple inits construction and arrangement, readily set up for the purpose of removin the cap, strong, durable, preventing the spilling of the contentsof the receptacle or bottle upon a person during the operation ofremoving the closure, efiicient in its use, and inexpensive.

With the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawings wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which come within the scope of the claim hereuntoappended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views:

Figure 1 is a vertical sectional view of a milk bottle provided with aclosure cap and showing the adaptation therewith of a cap removingdevice in accordance with this invention.

Fig. 2 is a view similar to Fig. 1 with a pulling element shifted to aosition at right-angles to that as illustrate in Fig. 1.

Fig. 3 is a top plan view 'of a removing device.

Fig. 4: is a vertical sectional view, broken away, and

Fig. 5 an inverted plan illustrated in the modified form.

Referring to the drawings in detail 1 denotes the body portion of a milkbottle, 2 the mouth, 3 a shoulder formed on the wall of the mouth and 4the closure cap for the mouth. The cap 4 is mounted against the shoulder3 and is of ordinary form of paper disk which constitutes a closure forthe mouth of the bottle.

The cap or closure removing device in accordance with this inventionincludes a guard 5, which is substantially dome-shaped in transversesection and is of such diameter to frictionally engage the periphery ofthe top of the body portion 1 of the bottle, when the guard is mountedthereon, and under such conditions provide a seal to prevent spillingremovlng the bottle closure. The guard 5, centrally thereof, is formedwith an upwardly projecting cylindrical extension 6, having its upperend closed by an integral disk 7 ,1 the latter is formed with .acentrally disposed opening 8, the wall of which forms a bearing for theshank of a combined cap piercing and pulling member to be presentlyreferre to The cylindrical extension 6 provides a housing for a portionof the shank referred to, as well as an extended bearing therefor.

Extending down through the opening 8 is a combined cap piercing andpulling membeer and which consists of an elongated shank 9, terminatingat its lower end in the base of a triangular shaped combined piercingand pulling element 10. Formed integral with the-shank 9 in proximity tothe element 10 is an annular stop 11 and formed integral with the shank9 exteriorly of the extension 6 is a head 12.

When using the device the guard 5 is mounted upon the top edge of thebody porthrough the cap 4, as illustrated in Fig; 1, after which theshank 9 is given a alf turn and then pulled upward, and the element 10will remove the cap 4 from within the mouth 2, the guard5 is thenshifted from ofi the body portion'l and the cap 4 is Patented Mar. 5,1918.

of the contents ofthe bottle when tion 1, and the element 10 is forceddown carried therewith, owing to the position of the element 10.

The guard 5 prevents the spilling of the contents of the bottle when thecap 4 is removed from the mouth.

In the modified form shown in Figs. 4 and 5, the guard which isindicated by the reference character 13 is formed with a series ofdepending spaced lugs 14:, which engage the closure cap 15 and hold thelatter on its seat. The combined cap piercing and pulling memberillustrated in Figs. 1 and 5 consist of an elongated shank 16, having areduced lower end 17 which terminates in a combined triangular-shapedpiercing and pulling member 18. The shoulder 19 formed by reducing thelower end of the shank 16 provides a stop which performs the samefunction as the stop 11. The guard 13 has an upwardly projectingcylindrical extension 20 through which extends the shank 16, the lattersnugly fits in the extension 20. The lugs 14, in connection with thebase, of the cap piercing and pulling member, couple the cap to theguardwhereby the guard and cap can be removed from the bottlesimultaneously.

What I claim is v Abottle cap removing device comprising a guardsubstantially convex intransverse section of a diameter to frictionallyengage the periphery of a bottle at the mouth end thereof to form aseal, a triangular-shaped element capable of piercing the bottle cap andadapted on a half turn thereof to have its base provide means forremoving the closure cap on the withdrawal of said element, a shankpermanently extending through said guard and formed integral at itsinner end with the base of said element centrally thereof, said guardhaving "means to provide an extended bearing for said shank, a head atthe outer end of said shank and permanently arranged exteriorly of saidbearing, and a plurality of spaced depending lugs integral with theinner face of the guard, surrounding said shank and capable of engagingthe cap to hold it down during the piercing operation and in connectionwith the base of said element coupling the cap to the guard whereby thelatter and the cap can be removed from the bottle simultaneously.

In testimony whereof I afiix my signature in the presence of twowitnesses.

THOMAS H. TAYLOR.
